Missouri Senate advances package of bills including water-export permitting, judicial-review changes and protections for students and children

The Missouri Senate on Wednesday, March 5, 2025, approved a series of bills including a water-export permitting law, a measure changing judicial review of agency decisions, and statutes addressing student associations, the minimum marriage age, hair-discrimination in K–12 schools, treatment courts and child-protection penalties.

The most contested measures received recorded roll-call votes; several passed by comfortable margins. Sponsors offered brief floor explanations before the roll calls. The measures are now sent to the next step required by legislative process.

Senate Bill 82 — water preservation Senator from Scott, sponsor of Senate Bill 82, described it as a measure “to help protect one of Missouri’s most precious resources, our water.” He said the bill would require entities seeking to export water from Missouri to obtain a permit, report annual water usage, make those reports public and allow the attorney general to investigate complaints. The sponsor said the bill includes a 30-mile limit for end users outside the state, a three-year permit subject to review, and metering and shutoff provisions to prevent unauthorized exports. Vote: 31 ayes, 1 no. Outcome: passed.

Senate Bill 221 — judicial review of agency determinations The sponsor (Senator from the second) described Senate Bill 221 as a judicial non-deference measure tied to the U.S. Supreme Court’s decision on Chevron deference. “This is merely the same thing, reaffirming our founders’ vision of the separation of powers, strengthening the legislative branch by making these issues a de novo review in the courts rather than siding with the administrative agencies,” the sponsor said. Vote: 25 ayes, 7 noes. Outcome: passed.

Senate Bill 160 — student associations at public institutions Senator from Stone characterized Senate Bill 160 as the “Student Freedom Association on College Campuses” measure, noting he introduced a substitute addressing concerns raised in earlier debate and bipartisan discussions. Vote: 23 ayes, 10 noes. Outcome: passed.

Senate Bill 66 — raise minimum marriage age to 18 The sponsor (Senator from the 20 fourth) said, “Senate Bill 66 would raise the age of marriage for all parties involved to 18,” citing concerns that existing law allowed 16- and 17-year-olds to be married in ways that could facilitate trafficking or visa-related exploitation. Vote: 32 ayes, 1 no. Outcome: passed.

Senate Bill 38 — school hair discrimination The sponsor (Senator from the ninth) framed Senate Bill 38 as an anti-discrimination measure for K–12 schools to protect hairstyles tied to cultural identity. On the floor the sponsor said the bill would prevent students from being removed from school or penalized for wearing hair in braids, Afros or dreadlocks. Vote: 32 ayes, 1 no. Outcome: passed.

Senate Bill 218 — treatment court divisions Senator from Livingston summarized Senate Bill 218 briefly: “The bill 2 18 establishes mental health treatment courts.” The vote was recorded as unanimous. Vote: 33 ayes, 0 noes. Outcome: passed.

Senate Bill 43 — child protection with penalty provisions Senator from Callaway presented Senate Bill 43 as a child-protection measure with penalty provisions. Vote: 31 ayes, 2 noes. Outcome: passed.

Senate substitute for Senate committee substitute for Senate Bill 466 — agricultural tax credits Senator from Celine said the measure removes sunsets for agricultural tax credits and makes technical corrections “to make sure that all the programs are being utilized to their fullest extent.” Vote (reported on the floor): 23 ayes, 9 noes. Outcome: passed.

What passed and what it means These votes represent the Senate’s approval to advance the listed bills. Passage in the Senate sends each bill to the next step in state procedure (remaining legislative steps or to the governor as required). Where the sponsor described implementation details (for example, SB 82’s permitting, 30-mile end-user limit, three-year permit term, required metering and shutoff), those provisions were discussed on the floor and are reflected in the bill record.

Quotes from the floor “This bill would help protect one of Missouri’s most precious resources, our water,” — Senator from Scott, on SB 82.

“This is merely the same thing, reaffirming our founders' vision of the separation of powers,” — Senator from the second, on SB 221.

“Senate Bill 66 would raise the age of marriage for all parties involved to 18,” — Senator from the 20 fourth, on SB 66.

Process notes and next steps Most bills were considered under third-reading procedures with sponsors offering short explanations and then proceeding to roll-call votes. Several bills (notably SB 82 and SB 221) drew extended floor inquiries and exchanges clarifying enforcement mechanics, permit duration, end-use definitions and oversight responsibilities. The Senate adjourned until Monday, March 10, 2025, at 4 p.m.
